Test Determination Process
New bus models must complete the full set of test procedures in order to be acquired by recipients of FTA capital funds. If a previously-tested bus is subsequently built with changes in components or configuration, then a determination must be made as to whether the change(s) are major changes that will require additional partial or full testing for that bus model.
The Bus Testing Regulation states at 49 CFR Part 665.7(b) that, “It is the responsibility of the recipient in dealing with a manufacturer, to determine whether a vehicle to be acquired is subject to [the requirements of the Regulation].” In situations where a manufacturer or other entity is uncertain whether the change(s) to a bus model are major changes, they may request assistance from FTA in determining whether the proposed changes would require additional full or partial testing.
Manufacturers and recipients are encouraged, however, to review the information available on this website before requesting FTA assistance. This information is being provided in the hope that it may answer many questions without the delay inherent in requesting an official FTA determination, and also to foster consistency in the application of the Regulation. When in doubt, however, we recommend that the parties request an official determination.
Thus, recipients and manufacturers should generally follow this process to determine whether a modified bus model is subject to additional testing:
Process for Submitting a Bus for Testing
